Photographers, makers and Raspberry Pi enthusiasts may be interested in a great project that provides inspiration and instructions on building your very own camera light meter. The Photon is a compact yet fully featured photography light metre that is powered by a Raspberry Pi Pico microcontroller.
The open source incident light meter called named Photon provides a fantastic affordable alternative to other light meter currently on the market. Check out the video embedded below to learn more about building your very own incident light meter using a little Raspberry Pi hardware.
“An incident light-meter can be an essential tool in photography (especially film photography with old cameras). The sophisticated computation baked-in to modern cameras devotes a lot of effort guessing ‘how much light is falling on the subject?”. If you have the option of getting to the subject and taking a reading, no guessing is required and everything becomes a lot easier. “

“Film photography is definitely worth a go. It isn’t better than digital, but it is different. The pacing, the delayed gratification, and the constraints make it a joy. One tool that it calls for (although we use one for digital pics too) is an incident light meter. We made a light meter with a mechanical keyboard switch for added satisfaction. We tested it, and put it in a video.”
“Photon reproduces the some of the functionality of more expensive tools, using a few inexpensive/readily available parts. Currently it measures ambient light brightness, as well as the red, green and blue components of the light, which might allow White Balance readings in future iterations.”
